Title says it all: My headphone amp (which I love, but have invertedly treated rough on occasion) stopped working. But it was no big deal: Everything could neatly be unscrewed; problem was a broken connection from the board to the USB socket. Bought a new nice one for less than a Euro, soldered it in, put the pieces back together, and voilà, works like a charm again! I feel proud of myself because I’m not the practical guy. But big kudos also to the guys from Fostex: This piece of equipment is maintenance-friendly like you rarely see these days!
